COUCH ROLL.

Application filed July 8, 1924. Serial No.'72 4, 853.

To all whom/it may concern:

Be it known that I, EMMITT S. ANDERSON,

I a citizen of the United States, residing. at

- Fort Francis,

in the Province of Ontario and Dominion of Canada, have invented certainnew and useful Improvements in a Couch Roll, of which the following is aspecification.

This invention relates to couch rolls especially adapted'to be used uponpaper making machines and it consists in the novel featureshereinafterdescribed and claimed,

An object of the invention is to provide a couch roll which willeliminate the necessity of compelling the use of the jacket laced aboutsuch rolls as is now the practice and which is objectionable owing tothe fact that the lacing frequently becomes twisted, thus forming lumpsand causing damage to the machine and the products.

With this object in view the structure comprises a roll consisting of abody or core made of cast iron and having a plurality of spirallydisposed ribs extending the full length thereof. These ribs are providedwith transversely disposed heads which are convexly curved therebypreventing the said head from having a tendency to develop corners orsharp angles while running. A series of-disks of pressed felt isthreaded upon the ribs and the core and the said disks extend the fulllength of the, core. Collars are mounted upon the end portions of thecore at the "ends of the series of disks. Gudgeous are mounted upon theends of the core and are disposed over the end portions of the shaft.which the core.

In the accompanying drawings Figure 1 is a longltudinal sectional viewof passes centrally through i the couch roll, V

The ribs extend the full length of the core. The core-is provided with alongitudinal contral bore in which is located 'a shaft 3. Y

Disks 4 of compressed felt are threaded upon the core land the disks areprovided with notches 5 which snugly receive the ribs and the headportions 3 thereof. Collars 6 are mounted upon the end portions of thecore and the said collars are disposed at the ends of the series ofdisks 4.. The collars are provided with notches 7 which receive the endportions of the ribs and the outer corner portions of the collars arebeveled as at 8. Gudgeons 9 are mounted upon the ends of the shaft 13and secured'by means of nuts 10, and the said gudgeons are provided attheir inner ends with disks 11 having of the ribs 2.

When the nuts are tightened upon the shaft the disks of the. gudgeonsforce the collars in close contact with the terminal 'disks and thedisks are compressed u on the holding the disk and they may be trued upby .grin

in order that their edge surfaces may lie in g the same cylindricalplane; After the disks f have upon the shaft 3, the mits 10 are-turnedup tightso-that' the disks will fit tightl against each other. This willgive the ro a hard surface and the'roll may then be soaked'in hot waterfor a suflicient length of time to permit the water to be taken up bthedisks whereby the said disks are shr upon the shaft and theirperipheries may be trued up by grinding in a usual manner. When the rollis not in use, the disks should be kept in a moist condition.

comprising a core having a central bore, a shaft located'in said bone,

spirally disposed ribs portions which are convexed transversely, disksthreaded upon the core and-the ribs, the ends of the core and the rib,gudgeons receiving the ends of the shaft and having disks which receivethe ends of the core and the ends of the ribs and provided upon the,periphery of the core, said ribs having head been assembled 10c Havingthus described the invention, what i nuts screwed upon the shaft andengaging the gudgeons.

2. A couch roll comprising a core having upon its periphery a series ofspaced spirally disposed ribs, the ribs being provided at their outeredges with head portions, disks of felt threaded upon the'core andtheribs, shoulders mounted upon the end portions of the core and the ribs,and the gudgeons mounted upon the end portions of the shaft and havingdisks which receive the end portions of the core and the rib.

dis-ks being shrunk by the application of moisture upon the core and theribs.

In testimony whereof I afiix my signature.
